Resum
Suction and microstructure play critical roles in the mechanical behaviour of loess, yet their effects on small strain (from 0·001 to 1%) shear moduli are not fully understood. In this study, shear moduli of loess with different microstructures and at different suctions are investigated and reported. Suction-controlled triaxial tests were carried out on two compacted and two intact loess specimens. Testing procedures include isotropic compression, wetting and shearing at constant mean net stres...
